Question

CISC 1115 Assignment 6 Write a complete program, including javadoc comments, to process voter statistics Input to Program: A file containing lines of data, such that each line has 2 integers on it The first integer represents a zip code (in Brooklyn or the Bronx), and the second represents the number of voters in that zip code. Output: All output may be displayed to the screen. In main: 1. Your program will read in all of the data in the file, one line at a time. The data will be put into 2 parallel arrays, the first called ZipCodes, and the second called voters. 2. Once populated, the program should print both arrays by calling a method that prints ONE array of integers. The method is called twice, once for each array. 3. The goal is now to split the data in the array according to zip code. All zip codes that begin with 112 are in Brooklyn, and those that begin with 104 are in the Bronx. Create 4 arrays, 2 for Brooklyn (zip codes and voters), and similarly 2 for Bronx. This can be done in main or in a method. 4. You should call a boolean method to determine whether a given zip code is in Brooklyn, i.e. begins with 112. The method returns true if the zip code is in Brooklyn, and false otherwise. You may do the same for the Bronx (or you may assume that all others are in the Bronx). 5. At the end, print the zip code in Brooklyn with the most voters, and the zip code in the Bronx with the most voters. This should be done by calling a method that finds the maximum value in an array of integers. Note: the method should return the index of the maximum value. INPUT DATA: You should have at least (not necessarily exactly) TEN lines of data in the input file.

Answer 1

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
